What is the primary focus of biometrics?

The primary focus of biometrics is the measurement of physical and behavioral characteristics. Biometrics involves the identification and verification of individuals based on unique traits, such as fingerprints, facial recognition, iris patterns, and even voice patterns. These characteristics are used to authenticate identity and provide secure access to systems and devices. This focus on individual physical and behavioral traits makes biometrics a widely used technology in security systems, personal devices, and law enforcement for identifying and verifying individuals accurately.

In contrast, financial risk assessment relates to evaluating the potential risks associated with financial investments or transactions, which does not pertain to the study of individual characteristics. Networking security deals with protecting computer networks from threats and unauthorized access, which is a different domain altogether. Machine analysis generally refers to the examination or assessment of machines or systems but does not specifically relate to personalized identification methods that biometrics encompasses.
